Does anyone know if it is possible to upgrade the E-GO Cruiser motor? maybe to this... http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=30784&aff=1242623
Will that speed up the Board or will it still be limited to the speed controller settings?
All answers are much appreciated.

Thanks!
 
Depends.. I believe I remember someone emailed E-Go and said that the speed wasn't controlled by their electronics. If that's the case, you could possibly change a pulley for a gearing ratio closer to 1:2.

I would probably ask them first. Doesn't hurt.

Mind taking a photo of the internal components of the E-go. I'd like to see it :)
 
I could send pictures when I get a chance to shoot them. What would happen if I just took off the old motor and replaced it with this... http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=30784&aff=1242623 ??
 
Take some photos of the internals and the mounts. We can then check a bit more and/or have you check specific things. I don't think anyone here has bought an e-go yet so we aren't aware of the actual components in the e-go besides what we see on their website as spare parts.

Ok. I will take pictures as soon as I can!
 
Were pictures ever taken? I have some of the same questions. I'd like to see if I could use the existing batteries and possibly switch out the motor or change a pulley so the gearing ratio is closer to 1:1.75 (I'm guessing)

According to the ego manual, it looks like its a 17T motor pulley and 35T drive pulley
 
I doubt changing the motor would do anything for u unless the motor
On it is getting hot. find out about the controller inside the board and if you can change the settings on it. Or figure out how many volts it runs on and then up that somehow and just hope the controller can take it
 
Hey guys no picture of the motor yet?
Been wondering I think its on the setting rather than on the motor to get more speed.
 
You cannot, the e-go use a sensor Brushless motor. Also, the wire they use really just only good for 400W and not more. Recently, I purchase the second e-go seems like they have also cut cost on the battery. My friend got a e-go which use a Samsung 18650-26F, and in sport mode he alway got the power. However, when I get my e-go last week I found that in sport mode it will be stopped automatically due to overloaded. So I open the battery and check it is not Samsung anymore, its some green packing battery (I guess might well be a Chinese one). So now I really have to forced to use Eco mode as in power mode it will always be stopped :/

Sounds like they were using authentic Samsung cells and down-sized to the Chinese cells. The Chinese cells aren't too bad though. They might have edited the on-board BMS to cut off sooner. Maybe, they got a bunch of returns, complaints, burned out motors?

Chinese cells life is not bad, but the power/current output makes a different. Samsung cells typically has about 50 m ohm resistance, but Chinese cells at least 20% higher. Which means at least 20% lower power output.

Given that the Samsung cells spec is only 2C, so the rated power output for the whole board battery = 7(Total number of battery in series) x 3.7(Rated V) x 15.6(A, 3 cells for which pack) ~ 400W

But when if use a Chinese cells, which means the power would at least 20% reduction :/

The way their BMS should just detecting the battery voltage to decide when to cut off, since the internal resistance increase the voltage should drop a lot faster when running

But I am still not 100% sure thats a Chinese cells, as the battery pack is covered by blue plastic. But 100% sure that they are not using the Samsung 18650-26F cell

Usually the 18650 in blue encasing is the Chinese cells. They are probably saving about $30-$50 per board with the knock offs. Is their a reason why they are only using 15.6 amps?

This is the manufacturer battery specification http://www.tme.eu/en/Document/40f2659afab69dbec94c09cc473a0e25/ICR18650-26F.pdf

Max.DischargeCurrent 5200mA (ambienttemperature25°C) <--- for each cell, so three cells = 5.2a X 3 = 15.6 a

So when they are using Samsung cells was only just enough for the motor rated output, now they changed to cheaper cells so now should below the rated spec =___=

Yeah, that sucks :( They should kept the same battery. Maybe complain :) They'll send you a real samsung set.

is ok I can live with that, just a bit slower :D it is still good value for the money
 
Ok this is crazy, I just using the board with Eco mode and it stopped automatically again due to overload but I am just riding on flat surface.

I have got many Samsung 18650 2000mah high power battery with me so I was going to change the battery myself. But when I open the blue plastic cover, the green battery is actually Panasonic 18650 2900mah. (Made in Japan)

I have really no idea what goes wrong now

I will try to change all the cable first, as the cable is actually quite slim
